采用热解吸法和傅里叶变换红外光谱（FT-IR）研究了H与沉积在硅衬底上的C2H4和C2H6固体薄膜在13k下的反应。H与C2H4反应，主要生成C2H6，次要生成C4H10。低温隧穿反应生成的C2H6产率较高，说明冷尘颗粒上发生了C2H4向C2H6的高效转化。在H与C2H6的反应中，没有检测到反应产物，说明固相中主要发生了H + C2H5→C2H6的复合反应。
The reaction of H with solid thin films of C2H4 and C2H6 deposited on the silicon substrate at 13 K was studied using the thermal desorption method and Fourier transform-infrared (FT-IR) spectroscopy. In the reaction of H with C2H4, the formation of C2H6 as a major product and C4H10 as a minor one was observed. The high yield of C2H6 formed from the low-temperature tunneling reaction suggests the occurrence of efficient conversion of C2H4 into C2H6 on the cold dust grains. In the reaction of H with C2H6, no reaction products were detected, suggesting that the recombination reaction H + C2H5 → C2H6 prevails in the solid phase.
